Among all the callers, only the device_list_add() function uses the second argument of alloc_fs_devices(). It passes metadata_uuid when available, otherwise, it passes NULL. And in turn, alloc_fs_devices() is designed to copy either metadata_uuid or fsid into fs_devices::metadata_uuid. So remove the second argument in alloc_fs_devices(), and always copy the fsid. In the caller device_list_add() function, we will overwrite it with metadata_uuid when it is available.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
